MOLD-BOX.

Specification of Letters Patent.

Patented Oct. 17, 1905.

Application filed September 17, 1904. Serial No. 224,905.

To all whom, it may concern:

Be it known that I, WVILLIs H. FISHER, a citizen of the United States, residing at Mount Gilead, in the county of Morrow and State of- Ohio, have invented a certain new and useful Improvement in Mold-Boxes, of which the following is a specification.

My invention relates to a new and useful improvement in mold-boxes for hydraulic stonemachines.

The object of the invention is to provide a suitable shaping or forming mold-box wherein a plurality of blocks may be simultaneously formed.

Another object resides in means acting in conjunction with the wing-plates for delivering the blocks when the said plates are swung outward.

Finally, the object of the invention is to provide a device of the character described that will be strong, durable, and efficient, simple to make, and one in which the several parts will not be liable to get out of working order.

With the above and 0x1 jects in view the invention consists of the novel details of construction and operation, a preferable embodiment of which is described in the specification and illustrated in the drawings, wherein Figure 1 is a front elevation. Fig. 2 is a plan view. Fig. 3 is an end elevation. Fig. 4 is a transverse vertical sectional view taken on the line w m of Fig. 2. Fig. 5 is a longitudinal vertical sectional view taken on the line y y of Fig. 2. Fig. 6 is a transverse vertical sectional View taken on the line 2 z of Fig. 2 and illustrating in dotted lines one of the wing-plates in its lowered position; and Fig.

7 is a partial perspective view of one of the cores, showing a cutter mounted thereon employed for severing the blocks.

The mold-box is designed to be used in connection with a suitable truck, which truck is provided with braces for supporting the wingplates when they are lowered.

In the drawings, the numeral 1 designates the top or platform of the truck, on which is disposed the bottom plate 2 of the mold-box. The mold-box is divided centrally of its length by a division-plate 3, supported upon the bottom plate 2 and secured thereto by dowel-pins 4. Projecting at right angles from the division-plate, at the center thereof, are partition-plates 5, arranged in pairs on each side. The partition-plates are spaced apart and are secured to the division-plate 3 by means of hinges 6, which are disposed within the space formed between the partition-plates,as clearly shown in the drawings. It will readily be seen that the mold-box is divided into four compartments, which are surrounded by the end doors 7 and wing or side plates 8. By forming the space between the partition-plates 5 and disposing the hinges therein the moldingcompartments are provided with smooth walls, and when it is desired to remove the blocks the said partition-plates are allowed to collapse or swing toward each other, and thus readily release the molded blocks. For the purpose of normally holding the partitionplates in position and also to protect the space between the said plates from falling sand, 8:0.

I provide the cover-plates 9, which are secured 5, and thus securely holding the said platesin.

position. It is apparent that by simply swinging the cover-plates 9 upward the wedge 11 is withdrawn from the bosses 12 and the partition-plates allowed to collapse, as hereinbefore stated. In each of the compartments I dispose a false bottom or delivery-plate 13, which are provided along their front edges with recesses 14. The plates 13 project beyond the outer faces of the wing-plates which rest thereon. The recesses 14 receive the bifurcated hinge members 15, which are formed integrally with the straps 16. I preferably provide five of these hinge members upon each wing-plate, and disposed between the strap members 16 are straps 17 which, together with the said strap members 16, are riveted to the wing-plates, so as to securely brace the same. The straps 17 are merged into bolts 17 at their lower ends, which pass through the projecting portions of the false bottoms 13. For bracing the wing-plates and the false bottoms together angle-irons 16 are suitably disposed between the straps and the strap members in the angles formed by the projecting portions of the said false bottoms and the wing-plates. The end doors are also provided with straps 17 and strap members 16, which carry at their lower ends the hinge members 15. However, there are no end lugs or projections from the false bottoms 13, which engage with the straps of the end doors. Hinge-leaves 18,-securely fastened to the bottom plate 2 of the mold-box, rest in recesses formed in the truck and project beyond the bottom plate between the furcations of the bifurcated hinge members 16. Pintle-rods 19, passing through the said parts, pivotally connect them, so that the wing-plates and doors may be readily swung outward. It will be observed that when the wing-plates are swung outward the false bottoms, being rigidly connected thereto by the bolts 17 and angle-irons 16, are caused to follow and to be swung upward and outward simultaneously with the wing-plates, thereby delivering the blocks upon the wing-plates, from which they may be readily removed. For the purpose of holding the end doors and the wing-plates together I pivot upon the end doors latches 20, which engage over pins 21, projecting from the outer face of the wing-plate.

It is to be understood that several sizes and shapes of blocks may be molded or formed in my mold-box, and in my drawings I have shown means for forming one of the various species which consists of suitable cores 22, mounted upon the false bottoms over which the plastic material from which the blocks or stones A are to be formed, is placed. Di-

vision-boards 23, also carrying cores 22, are

then placed upon the above-mentioned material, over which is spread a second batch of plastic material for forming the blocks B. By observing the drawings it will be seen that two blocks may thus be formed in each compartment, and by providing four compartments eight blocks may be formed or shaped at a single operation. Pallets 24 are placed in each compartment against the wingplates 16, so that when the same are swung outward to the position indicated in Fig. 6 the blocks will rest upon the pallets, and thus may be easily removed from the wing-plates without injury.

In some instances it is desirable to mold blocks of intermediate lengths, and for expeditiously and efficiently accomplishing this end I provide a cutter 25, having a right-angular flanged base 26, by which it may be readily secured to the face of one of the cores 22. This cutter is of such a height as not to project through the upper surface of the compressed block, thus obviating the liability of its injuring or defacing the compression-head. The portion left unsevered, however, is so slight that the parts of the block may be readily severed when they are removed from The division-boards 23, bearing the cores 22, are then placed upon the plastic materiahand a second batch of plastic material is then spread over the said last-named parts. Enough material. is placed in each layer to allow the same to be compressed to form blocks of the desired thickness, which varies according to the style of block desired. The box, as before stated, being mounted upon a suitable truck, is now run into the press. The compression-head of the press is forced down upon the plastic material and pressure applied thereto until the said material is compressed and the blocks formed. The compressionhead now being raised, the mold-boX is removed from the press and the cover-plates 9 swung upward, so as to withdraw their wedges 11 and allow the partition-plates 5 to collapse or swing toward each other. The latches 20 then being raised, the end doors 7 are allowed to swing downward. The molded blocks are now ready to be delivered upon the wingplates, which is accomplished by swinging the said wing-plates outwardly and downwardly until they lie substantially parallel with the bottom 2 of the mold-box. As before stated, when the wing-plates are swung downward the delivery-plates or false bottoms 13 are swung upward, which carries the blocks therewith and causes the same to rest upon their sides upon the pallets 24:, which position they occupy when the wing-plates are brought to the position shown in dotted lines in Fig. 6. The blocks may now be readily removed and the operation repeated. It is to be understood that several of these mold-boxes may be used, which greatly expedites the making of artificial stone.

Having now fully described 'my invention, what I claim, and desire to secure by Letters Patent, is

1. In a mold-box, the combination with hinged wing-plates, of delivery-plates having projections connected to the wing-plates and adapted to be moved simultaneously therewith.

2. In a mold-box, the combination with hinged wing-plates having projections, of delivery-plates having projections in engagement with the projections of the wing-plates.
